## Discrepancy

RETURNED DEPARTURE DUE TO A NR 2 MAIN LANDING GEAR, TIRE SEPARATED AND ANTI-SKID LIGHT ILLUMINATED AFTER TAKEOFF. ALSO SYSTEM-A HYDRAULIC PRESSURE WENT DOWN TO 42 PERCENT. AN EMERGENCY WAS DECLARED AND LANDED WITHOUT INCIDENT.  THE AIRCRAFT WAS GROUNDED.    MAINTENANCE CONFIRMED THE TIRE SEPARATION CAUSED DAMAGE TO HYDRAULIC FITTINGS AND WAS THE ISSUE FOR THIS EVENT.
